I think you're missing the point. Its supposed to be cheaper. Hence the use of plastic and cheaper components. All the low-cost Android phones have what you call "outdated components" but I don't see you (or any other anti-Apple people) complaining about that.
I mean I wish I could buy a Ford Focus that completely recapitulated a Ferrari 458 spider but that high-end, cutting-edge technology in the Ferrari is expensive. Over the next few decades some of it will eventually make it into the 15k car but it will of course be "outdated" compared to what the new Ferraris have at that point.
The point is if you want the newest, best technology you have to pay for it. If you want to spend less money then be content with technology that has already been used in the previous high-end devices.
